While bidding adeu you may say Good riddance to contact lenses too.
Imagine getting up in the morning and looking at the alarm clock with your naked eyes. You then grab your smart phone to check on your email and the latest from your friends on face book. While eating breakfast you skim through the newspaper. Continuing the trend, you drive with no glasses to work and then go on to play golf. After playing the best golf of your life, you get a quick swim in which is a pleasure without glasses or contact. On way home you pick up groceries without squinting. Then you cut some organic veggies for a nice dinner. Catching up on bedtime reading, you wonder why you did not get this unbelievable rejuvenating therapy before.
How is that possible? But first why not talk about why you even need glasses for reading. or I think I may have presbyopia.
Presbyopia is medical jargon for ageing eyes.
What causes presbyopia?
There is increasing stiffening of natural lens and decreasing strength of eye muscles. The zoom mechanism of the natural lens undergoes deterioration.
Old is difficult to define. This condition is present in mid forties. It may appear a little earlier in farsighted people. People with smaller pupils may display a delay in onset of presbyopia.
We have a few choices to overcome this natural malady.
Pie is the creme de le creme of methods to rejuvenate ageing eyes. Let us explore how it is superior to other methods which combat effects of taking too many revolutions around the sun.
PIE is more advantageous than Glasses
Heck yeah. You agree with this or you would not be reading this page.
It’s safe to say PIE overcomes all these nuisances.
Pie gives binoucularity which is better than Monovision
This is a process of setting the focus of one eye on close-up objects and the focus for your other eye on far-away objects. In doing this, your brain combines the two images to create a clear picture. This is a relic from the twentieth century. Primary disadvantage is one looses binocular vision.
PIE allows you to preserve binocular depth of field vision.
Brain prefers PIE to multifocal contact lenses
Multifocal contacts move with every blink. The image presented to the brain fluctuates confusing it. That is why many people are not able to adapt to multifocal contact lenses.
PIE are stable and do not move. Brain neuroadapts improving vision.
Contact can lead to sight threatening cornea infections for as long as you wear them.
PIE is not exposed to the elements or bugs.
Types of PIE
Multifocal PIE let you see far and near
These include the ReZoom, ReSTOR, Symfony and Tecnis lenses. Multifocal IOLs are lenses that have concentric rings of varying focal power, like a bullseye. Some rings provide focus for near objects, others for mid-range objects, and some for seeing objects at a distance.
The Tecnis Multifocal Foldable IOL also has concentric rings for different distances. It received FDA approval in January, 2009 for use in cataract surgery, where the natural lens is replaced. In the clinical trials most participants achieved 20/25 distance vision or better and 20/32 or better for near vision. It is designed using Wavefront data – the same precise level of information that is gathered when you are having Wavefront LASIK.
Accommodating PIE implants mimic natural lens
These lenses are designed to change focus. An accommodating IOL allows you to see distant objects, and then is can change focus and allow you to see objects that are close up. The only accommodating IOL approved in the United States is the Crystalens. This was true in 2005 and is still true in 2014. We even have toric crystalens called trulign.
